Boffins bust biometrics with inkjet printer

Boffins from Michigan State University have loaded up an inkjet printer with cartridges designed for printing electronic circuits, and used the output to fool smartphone fingerprint sensors.

All that's needed is a scan of the victim's fingerprint (reversed so it presents the right way when printed), and a suitable inkjet printer loaded up with ink and paper from printed electronics specialist AGIC.

In their paper (PDF) the researchers, Kai Cao and Anil Jain from the university's Department of Computer Science and Engineering cracked a Samsung Galaxy S6 and a Huawei Honor 7. It's a much simpler approach than the “gummy bear fake fingerprint”, which needs materials like latex milk or white wood glue.
